For the purpose of investigation the inertial behaviour of the crystalline lens, the COMSOL Multiphysics® software was used to create a 2D multi-physics model of the porcine eye globe, by using the Fluid-Structure Interaction (FSI). The geometry of the porcine eye model was adapted from ... En savoir plus

In regular biosensors, the detected bacteria have to be in drawn towards the sensing area. To increase the sensitivity of the biosensors, bacteria should be drawn towards the sensing area, which can be achieved by dielectrophoresis (DEP). DEP is a mechanism which is used to move ... En savoir plus

Among the different uses of primary energy in the industrial and residential sectors, refrigeration and air conditioning systems consume around 17% of the electricity produced worldwide [1], reaching dissipated powers of approximately 2000 TWh [2]. These devices are based on the vapor ... En savoir plus

Piezoelectric materials are substances that can convert mechanical energy into electrical energy and vice versa. This is called the piezoelectric effect. When a piezoelectric material is squeezed or stretched, it creates an electric charge. This is because the material's atoms are ... En savoir plus

Ultrasonic flow-cell reactors are used for many industrial applications, where fluid substrate is sonicated in a small region, where very high ultrasonic acoustic power is present. The electromechanical transducer (converter) that drive the sonotrode inside the flow-cell is designed in ... En savoir plus

MEMS microphones have been widely adopted in a variety of consumer electronic systems. To ensure clear speech transmission and avoid degradation of important signals, careful tuning of microphone port geometry is essential to mitigate wind-induced airborne noise. This additional noise ... En savoir plus
